Thank you so much for your replies, currently I am taking anti anxiety medication and an anti depressant.

For the constant headaches, paracetamol, aspirin and Ibuprofen hardly seem to touch the headaches.

My doctor hasn't actually diagnosed me with anything, he just says the medication will take several months before I see a change. He seems to think its anxiety and depression but they can also be symptoms of PCS.

Nobody remembers if I hit my head but they all say I got rugby tackled hard.

When I mentioned PCS to the doctor, he said, I have had a CT scan which was negative so it can't be that, well most people who have had a concussion will have a negative CT scan.

The medication I am on is:

Valpromide 300mg (morning and evening)
Oxazepam 5mg (morning and evening)
Chlorpromazine (12.5mg morning and 25mg evening)
Escitalopram 10mg in the morning

Thanks for everyones help.
